The Load Capacity Usage percentage, or Load Evaluator Index, for a Citrix Virtual Apps and Desktops or DaaS multi session machine delivery group, represents the percentage of resources allocated to that delivery group, that is in use by virtual desktop or application sessions. It is the ratio between the sum of all measured Load Indexes, and the sum of all maximum Load Indexes for the multi session machines in the delivery group. A Load Index represents the load on a multi session machine.

The Citrix Print Manager Service is part of the Citrix Virtual Desktop Agent (VDA) software which runs on a single or multi session machine. It is used for the Citrix Advanced Universal Printing Architecture. It takes care of the client printer mappings between a user client and the VDA within an ICA session. This service heavily relies on the Windows Print Spooler service which spools print jobs and handles interaction with the printer.

The Citrix Audio Redirection Service is part of the Citrix Virtual Desktop Agent (VDA) software which runs on a single or multi session machine. It is responsible for redirecting audio over the Audio Virtual Channel to be used within the ICA session. If this windows service has stopped running, users having a virtual desktop session to the respective session machine have no sound.

A Citrix Virtual Apps and Deskstops or Citrix Desktop as a Service deployment does not comprise Citrix components only. For instance, SQL databases are crucial components of every Citrix VAD stack and therefore need to be monitored and managed intensively. Besides whether your Citrix delivery controllers have proper access to them, you obviously need to track the database performance and capacity as well.

NetScaler licenses could enforce bandwidth throughput limitation which results in the NetScaler dropping network packets. MetrixInsight for NetScaler tracks packets being dropped due to NetScaler license limit exceedance.

Are you aware when Denial-of-Service (DoS) JavaScript triggers occur on your Citrix NetScaler devices to block DoS attacks? Do you know when exceptions are made based on 'valid' DoS cookies? MetrixInsight for NetScaler monitors for these occurrences and alarms you whenever this happens (too often).

When your NetScaler appliances are running in a High Availability (HA) pair you should be aware when failovers occur, as this indicates an issue on one or both of the appliances, which you need to solve before both the appliances have the same issue. In the case the latter happens, or is already the case, the appliances will fail over continuously, which is known as HA failover ‘flip-flopping’.

Are you aware when an administrator has forgotten to save configuration on a Citrix NetScaler device? If configuration is not saved after a configuration change it will get lost when the NetScaler appliance restarts. This can obviously have severe consequences. MetrixInsight for NetScaler will alarm you whenever unsaved configuration is detected.

Certificates have a limited validity time and need to be renewed once in a while. Expired certificates may impact the availability of services. MetrixInsight for NetScaler monitors the expiration state of NetScaler certificates and alarms you when they are going to expire and have been expired.
